Guessing time again
Two community-nominated levels will appear in the final set.
I have nearly nothing to go on here, so I'm going with my favourites here: Temple of No Key and Caveat Emptor. I think Death Box is too busted to be fixed and included.
The 131, 144, 147, and 149 spots are held by four different CCLP4 staff members
131: Jeffrey (no idea, I originally had The Illuminati and An Exit Too far (not by a staff member) as candidates here)
144: J.B. (Japanese Game Show or Color Coordination?)
147: Tyler (Gimmick Isle?)
149: Josh (Mental Marvel Monastery)
The highest fun rating not included in CCLP4 was 4.35. The lowest fun rating included was 3.33.
Double-time Warehouse, any level with blobs, walkers or invisible walls
The highest and second highest rated level for "fun" in CCLP4 voting were ranked 152nd and 588th in CCLP1 voting, respectively.
The 588th ranked one was probably one that was considered too difficult for CCLP1. I heard Repugnant Nonsense got very good ratings, I guess it's in top two.
Two levels are in the same slot as the level their walls were originally from.
I'm not very good at recognising walls, I only know of the ones that were entered in Create competitions. My guesses are Chilled to the bone (#136), The Salt Mines (#105).
